Abstract
Description
- 1. Field of the Invention
- The invention relates to air guns and more particularly to a magazine for an air gun, the magazine having a ratchet loading mechanism.
- 2. Description of Related Art
- There is a conventional magazine for an air gun having opposite first and second ends, the magazine comprising a rotary clip attachment adjacent to a selected one of the first and second ends, and a rotary clip rotatably connected to the rotary clip attachment and including a rotary clip cylindrical end surface. The rotary clip attachment has a wall defining a rotary clip wall surface opposing the rotary clip cylindrical end surface. Thus, at least a portion of the rotary clip wall surface gradually moves away from the rotary clip cylindrical end surface in an inclined manner and in a direction of the selected one of the first and second ends.
- Notwithstanding the prior art, the invention is neither taught nor rendered obvious thereby.
- It is therefore one object of the invention to provide a magazine for an air gun comprising a first shell; a second shell releasably secured to the first shell; a passage formed by both the first and second shells; a rotatable shaft including a lengthwise groove on a surface, a transverse slot on the surface, the transverse slot connecting to and communicating with the lengthwise groove, and two opposite mating members on one end; a pulley rotatably put on the rotatable shaft and having both ends rotatably secured to the first shell and the second shell respectively; a ratchet mechanism mounted on the pulley; a pin inserted into the pulley to dispose in one end of the lengthwise groove; a line having one end wound on the pulley, the line extending through the passage to have an other end engaged with a projectile support in the passage; a biasing member put on the line and biased between the pulley and the projectile support; and a spring biased knob disposed on an outer surface of the first shell and including two opposite corresponding mating members engaged with the mating members, the spring biased knob being releasably secured to the rotatable shaft; wherein a pressing of the spring biased knob until being stopped; a clockwise turning of the spring biased knob until stopped disposes the pin at an other end of the transverse slot; a continuous, clockwise rotation of the spring biased knob winds the line around the pulley and compresses the biasing member until being stopped; a counterclockwise rotation of the spring biased knob until being stopped; and a release of the spring biased knob until being stopped disposes the pin at one end of the lengthwise groove so as to create a space in the passage for projectile loading.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is a perspective view of a magazine for an air gun according to the invention; -
FIG. 2 is an exploded view ofFIG. 1 ; -
FIG. 3 is an enlarged view of a portion ofFIG. 2 ; -
FIG. 4 is an exploded perspective view ofFIG. 3 ; -
FIG. 5 is a perspective view of the assembled components ofFIG. 4 with the first shell removed showing first operations before loading; -
FIG. 6 is a perspective view of the rotatable shaft ofFIG. 5 ; -
FIG. 7 is a view similar toFIG. 5 showing second operations before loading; and -
FIG. 8 is a perspective view of the rotatable shaft ofFIG. 7 . - Referring to
FIGS. 1 to 8 , amagazine 1, consisting of afirst shell 18A and asecond shell 18B threadedly secured together, for an air gun (e.g., compressed-air toy gun) in accordance with the invention comprises the following components as discussed in detail below. - A U-shaped
passage 10 is provided. Acurved line 12 has one end terminated at apulley 20 of a cylindricalrotatable shaft 2 and the other end engaged with a bottom of aprojectile support 19. In detail, one end of theline 12 passes through ahole 14 through a cylindrical,hollow pulley 20 and wound thereon. Further, agear 13 is mounted on one end of thepulley 20. Furthermore, thepawl 13 cooperates with apawl 26. Ahelical spring 11 is put on theline 12 and biased between therotatable shaft 2 and thesupport 19. Twobearings 23 are provided in which one bearing 23 is disposed in a stepped-diameter passageway 24 through thefirst shell 18A and theother bearing 23 is disposed in a stepped-diameter passageway 25 in thesecond shell 18B. One end of thepulley 20 is rotatably disposed in one bearing 23 and the other end thereof is rotatably disposed in theother bearing 23. Apivot pin 27 has one end fastened in thefirst shell 18A and the other end fastened in thesecond shell 18B. Thepivot pin 27 is loosely inserted through thepawl 26. A bottom of thepawl 26 is supported by a top of atorsion spring 28 anchored in aspring receptacle 29 formed on an inner surface of thefirst shell 18A. Thus, thepawl 26 can be pivoted to allow thegear 13 to rotate in only one direction (e.g., clockwise direction). Apin 15 is inserted into thepulley 20 and moveable disposed in alengthwise groove 22 and atransverse slot 21 both formed on therotatable shaft 2. Further, thegroove 22 and theslot 21 communicate each other and form a 90-degree bent member. Therotatable shaft 2 comprises twoopposite recesses 32 on one end surface. Therotatable shaft 2 is rotatably fastened in thepulley 20. A cup-shaped knob 3 comprises twoopposite projections 31 on an inner surface complementarily disposed in therecesses 32, and aknurled rim 30. Ascrew 16 is driven through a central opening of theknob 3 into therotatable shaft 2 so that theknob 3, therotatable shaft 2, thepulley 20, and thegear 13 can be co-rotated. Ahelical spring 4 is biased between the inner surface of theknob 3 and acircular well 17 formed on an outer surface of thefirst shell 18A. Thus, theknob 3 is resiliently disposed in thewell 17. It noted that thepin 15 is moveably disposed in one end of thegroove 22 distal theslot 21. - A projectile loading operation is discussed in detail below. As shown in
FIGS. 5 and 6 , an individual may press theknob 3 as indicated by arrow a until thepin 15 is stopped (i.e., disposed at the other end of thegroove 22 and one end of the slot 21). The individual may further clockwise turn theknob 3 as indicated by arrow b until thepin 15 is stopped (i.e., disposed at the other end of the slot 21). Thereafter, the individual may continuously, clockwise rotate theknob 3 to wind theline 12 around thepulley 20 with thespring 11 being compressed until being stopped. It is noted that thegear 13 is allowed to only rotate clockwise due to the provision of thepawl 26. - As shown in
FIGS. 7 and 8 , the individual may counterclockwise rotate theknob 3 as indicated by arrow c until thepin 15 is stopped (i.e., disposed at the other end of thegroove 22 and one end of the slot 21). The individual may further release theknob 3 until being stopped as indicated by arrow d until thepin 15 is stopped (i.e., disposed at one end of the groove 22). Finally, the individual may load a plurality of projectiles into a space between theprojectile support 19 and a top opening of thepassage 10 for temporary storage. This completes the loading operation. - While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
